An "atmospheric river" is a colorful term for a sinuous plume of moisture that travels up from the tropics — a single plume can carry more water than the Mississippi River at its mouth. But new research shows that atmospheric rivers are also among the most damaging weather systems around.

The atmospheric rivers that soaked California this winter did some good — they ended an epic drought in the state.

Sitting inside a glass-encased cockpit, two men fiddle with joysticks controlling giant claws outside. They look like they're playing at a vending machine at a mall, where you try to grasp a stuffed animal. But these are engineers. The claws they're manipulating are as big as houses, and they're sifting through hundreds of tons of garbage thrown away by the world's largest consumer class.

On the day before President Trump's inauguration, the outgoing Obama administration passed a last-minute directive, banning the use of lead ammunition and fishing sinkers on federal land.

Recently, the deteriorating health of a bald eagle showed the effects of lead poisoning. Obama's regulation is intended to protect wildlife from exactly that.

But hunters are hoping Trump will soon overturn it.

Last week, an officer from the Pennsylvania Game Commission brought a bald eagle to the Carbon County Environmental Education Center in Northeastern Pennsylvania.

Polar bears aren't the only beloved Arctic animal threatened by climate change. Scientists believe reindeer are at risk as a warming world makes their main winter food source disappear.

But reindeer on one Alaskan island are surprising researchers.

And that surprise doesn't just come from the fact that the reindeer are hard to spot.

On St. Paul Island, Lauren Divine of the EcoSystem Conservation Office was not having luck seeing a herd of 400 reindeer, even on this treeless island with tundra as far as the eye can see.

Living by the ocean might sound nice, but in the era of climate change, it's a risky proposition.

As sea levels rise, coastal residents are faced with tough choices: try to fortify their homes, move to higher ground or just pull up roots and leave.

Homeowners in Nahant, Mass., are grappling with these wrenching questions. The community lies on a rocky crescent moon of land in the Atlantic Ocean just north of Boston.

For its entire history, it has been at the mercy of the ocean.

Oklahoma Attorney General Scott Pruitt has been confirmed as the next administrator of the Environmental Protection Agency, an agency Pruitt has long criticized.

The Senate approved Pruitt on a 52-46 vote Friday afternoon, with two Democrats — Joe Manchin of West Virginia and Heidi Heitkamp of North Dakota — voting for his nomination. Republican Susan Collins of Maine voted no.

It's been a long week. Take a moment — or even a minute! — to watch something beautiful.

Since going over capacity last week, the water level in the Oroville Dam has dropped, but it's still at a higher level for this time of year than the previous 16 years.

On Jan. 25, President Trump signed an executive order instructing construction to begin on a wall along the U.S.-Mexico border. Environmentalists and civil rights activists say the proposed wall on the southern border with Mexico is a threat to the environmental rights of the people who live on both sides of the border.

The Environmental Protection Agency has a pretty simple mission in principle: to protect human health and the environment. It's a popular purpose too. Nearly three out of four U.S. adults believe the country "should do whatever it takes to protect the environment," according to a 2016 survey by the Pew Research Center.

Political support for the EPA, though, is less effusive.

The economy in southwestern Pennsylvania has been hit twice, once by the collapse of big mining and steel employers, and again by the environmental destruction that accompanied those industries.

It's a part of the country that voted heavily for Donald Trump.

Ashley Funk grew up an hour outside Pittsburgh. The area feels kind of left behind with buildings named after mining companies and polluted ponds turned fluorescent, alarming colors.

Wind power is the largest source of renewable energy in the United States. But a broad swath of the country has had no large, commercial wind farms — until now. A new one with 104 towers is up and running near Elizabeth City, N.C., where it spans 22,000 acres.

You know those nasty brown spots that can ruin an otherwise perfectly delicious apple? Those spots and other problems — like blossom blight and yellow leaves — are often caused by fungi. Apple growers usually fight back with fungicides, but a new study has found that those fungicides could be hurting honey bees.

"The long-standing assumption is that fungicides won't be toxic to insects," says May Berenbaum, an entomologist at the University of Illinois Urbana-Champaign.
